BUTTON-V-ATTACHING MEC ANISM;

To all whom it may concern Be it known that I, LEONARD R. CARLEY, a subject of the King of Great Britain and Ireland, residing at Waterbury, in the county of New Havenand State of Connecticut, have invented certain new and useful Improvements in Button-Attaching Mechanism, of which the following is a specification, reference being had therein to'the accompanying drawings.

The invention relates to machines for attaching buttons or similar articles to a garment or other fabric, and more particularly to that type in which the article is attached by a metallic fastener.

It is the object of the invention to insure a positive operation of the -machine,avoiding danger of false registrationof the attaching shank with the button, or thebending of the shank during the penetratlon of the same through the fabric.

To this end the invention consists in the construction as hereinafter setforth.

In the drawings: Figure 1. is a side eleval tion of a button attaching machme to which my improvements are applied; Fig. 2 is a front elevation of the attachment mechanism; Fig. 3 is a longitudinal section thereshank.

The drawings also show a specific construction of button which is provided with a cross bar around which the prongs are hooked or clenched, butthis also is not essential to the invention; n

A is the frame of the button attaching machine; 13 is the reciprocatory plunger for clenching the button shanks; and C is the stationary support or anvil, preferably slightly recessed at C to receive the head of the fastener.

D and D are jaws above the anvil and projecting from opposite sides of thesame, said jaws being provided with grooves 'E for receiving the prongs of the fastener. The jaws D and D. are carriedby arms Fand' F, which embrace the anvil D and at their" lower ends are pivotally connected to each other by a link G. This link is also in ena em .W t a l ili h h i l?

ported upon the anvil C. Any suitable .mechanlsm (not shown) may be employed Patented Apr. 11, 1916.

Application filed December 27, 1913. Serial No. 808,928. i

for engaging the fasteners with the grooves.

.E in the jaws, but as illustrated in Fig. 4,

the jaws are provided with a tapering entrance slot E which will guide the prongs 111130 the grooves. 'W hen the prongs of the fastener are thus engaged, a button, as indicated at M, is placed upon the plunger B, while the cloth or fabric lV is arranged between the: button and the prongs of the fastener, as indicated in Fig. 5. The plunger B is then .depressed, and simultaneously the jaws D and D are moved downward so as to permit the points of the prongs'to penetrate the cloth, but at the same time to guide and support them during this movement. After the points penetrate the cloth and embrace the cross-bar M of the button, they will be turned by-the concave surface B of the plunger B, as shown in Fig. 6. The jaws D and D are then laterally withdrawn and the plunger completelydepressed, as shown in Fig. 7. i j 1 I For effecting the movement just de-. scribed,'the arms F and 'F, which carry the jaws D and D, are provided with suitably cammed faces crammed. faces on the anvil C and complementary 'cammed membersN and N on opposite sides thereof. In the initial position shown in Fig. the cams and N permit a slight spreading of the jaws sufficient for the introductloirof the prong fastener into the grooves E. When, however, the arms Fand F are drawn downward by the op eration of the cam J and leversI and'H,

projecting; portions 0 upon the arms F and F engaging with portions P I of the'cam members N and N, will hold the jaws. D

and D in closedposition, as shown in F 2. The jaws-remain in this closed position during 131G611. further depression and the penetration of the clothby the sharp ends of the prongs until the, position shown in F1g.j 6 isreached, in which position the ends of the prongs havev been turned, as indicooperating with cated. A further downward movement of the arms F and; F will bring the cam faces P on said arms into engagement with vhe cam faces (,2 on the anvil G, which, by their engagement, will cause the spreading of said arms and the lateral Withdrawal of the jav-2s,'as shown in Fig; 7 Thismovement is permitted by the cam members N and N, which are cut away at R to form recesses. The plunger B continues its downward movement during the operation just de scribed, and consequently completes the clenching of the prongs and the securing of the button to the fabric. The plunger B and the arms F and F are then returned to their initial positions ready for a repetition of the operation.

From the description just given, it will I be understood that the prongs of the fastener are supported and guided miti l'they are completely engaged with the button,

thereby avoiding danger of misplacement by the resistance of the cloth through which they are passed. It is obvious that thesame result could be obtainedwith a fastener having but a single prong. What I claim as my inventlon 1s:-

1. The combination with relatively mov: I able members for respectively holding a buttonand a fastener upon opposite sides withdrawing said holding means from said fastener.

2. The combination with relatively movable members for respectively holding the button and a fastener upon opposite sides of the garment, of means engaging the shank "of the fastener intermediate its ends and positively guiding and holding the same-1n registration with the eye of the button during the relatlve movement 1 thereof, and means for wlthdrawlng. sald engaging ,means near the end of said relative movement.

3. The combination with relatively movable members for respectively holding button and a fastener having a pointed ing said fastener in registration with the shank, of means for engaging said shank near the point end thereofcand positively holding the same in registration with the eye of the button during the relative movement of the parts, means for causing said guide to travel toward the rear of the shank during the movement of said fastener into engagement with the eye of the button, and means for withdrawing said guide from be tween the fastener and buttonto permit the tightening thereof.

5. The combination with relatively movable members for respectively holding a button and a fastener having a pointed shank upon opposite sides of the garment, of means for engaging said shank near the point endthereof and positively guiding the same in registrationwith the eye of the button during the initial relative movement. means for shifting the engagement of said guide toward the rear of the shank during the continued relative movement of the button and fastener, and means for finally withdrawing said guide from between the fastener and button topermit the tightening thereof.

6. The combination with relatively movable members for respectively holding a button a fastener having a pointed shank on opposite sides of the garment, of a positive guide for said shank holding the same in registration with the eye of the button comprising a pair of oppositely moving aws, means "for closing said aws around. said shank adjacent to the point thereof during the initial relative movement,means for retaining said jaws in engagement withsaid shank and causing the 'button and a fastener having a pointed shank, of a pair of oppositely moving jaws together forming grooved guide bearing for said shank near the point end thereof and for positively holding the same in reg istration with the eye of the button, means for maintaining the engagement of the guide during the continued relative movement of parts but permitting it to travel to ward the rear of the shank, and means for finally withdrawing the jaws to permit the clenching of the fastener. V

8. The combination with relatively movable members for respectively holding a button and a fastener having a pointed shank, of a guide comprising a pair of oppositely movable jaws embracing the holder for the fastener, means for moving said jaws relative to said holder for the fastener during the relative movement of the button holder, and cams operating during the movement of said jaws to close the same in engagement with the shank near the point end thereof to maintain said engagement while traveling toward the rear of the shank and then to release said engagement and separate the jaws during the final relative movement of the button and fastener holders.

9. The combination with a plunger member forming a button holder and a member therebeneath on which a fastener is supported, of a pair of positively guided jaws embracing said fastener member, means for moving said jaws in the-plane of movement of said plunger toward said fastener supporting member, and cams operating during said movement for causing first, the closing of said jaws about the shank of the fastener near the point end thereof then maintaining the jaws closed until the same are near the rear end of the shank and finally separating the jaws to withdraw the same from about the shank.

10. In a button attaching machine a holder for a fastener having a shank, in-

eluding means for positively engaging said shank, and means for disengaging said shank-engaging means from the shank by a movement parallel with the shank.

11. In a button attaching machine a holder for a fastener having a shank, said holder positively engaging the shank intermediate its ends, means for preventing disengagement of the holder from the shank during a portion of the operation, and means for subsequently disengaging the holder from the shank by a movement parallel with the shank.

12. In a button attaching machine a holder for a fastener having a shank, means for engaging said holder with the shank intermediate its ends, means for preventing disengagement of the holder from the shank during a portion of the operation, and means for subsequently disengaging the holder from the shank moving said holder laterally from said shank. V

13. In a button attaching machine a holder for a fastener having a shank comprising jaws on opposite sides of the shank,

means for causing said jaws to laterally engage said shank intermediate its' ends, and 1 gage said shank, means for positively holding the jaws from separating during the engaging operation, and means forsubsequently laterally disengaging the jaws from the shank.

15. In a button attaching machine, a holder for a fastener having a shank, comprising jaws on opposite sides of the shank, means for causing said jaws to move sub stantially parallel with said shank, means for positively holding said jaws from separating during a portion of the movement, and means for subsequently withdrawing the jaws.

16. In a button attaching mechanism a combination of relatively movable members having cooperating cams thereon, one of said members comprising a holder for a fastener having a shank, said cams causing the engagement and disengagement of said holder with said shank.

17. In a button attaching machine, relatively movable members for respectively holding a button and a fastener having a shank, and means surrounding the shank for positively holding the same in registration with the eye of the button during the relative movement of the members.

18. The combination with relatively movable members for holding a button and a fastener upon opposite sides of the garment, said fastener having a pointed shank for piercing the garment, of means positively engaging said shank for positively guiding and holding said fastener in registration with the eye of the button during the relative movement thereof.
